Green Wireless Network Deployments in Indoor Environments Using Radio-over-Fiber Distributed Antenna Systems

Distributed antenna systems (DAS) are known to improve coverage and performance of wireless communications in indoor environments. In the present paper, we propose a method to determine the position of distributed antennas that optimizes the network capacity for a given deployment scenario. We also consider power consumption measurements of commercially-available Wi-Fi access points and dongles, in order to quantify the energy efficiency of a DAS using Radio-over-Fiber (RoF) technologies. Our results show that there exists an optimal number of distributed antennas for a given topology of the indoor environment.
